The way to cause effective local change among people you know is to build meaningful relationships with psychological safety. They will figure out your political opinions with time, and they will be more subtly but durably influenced.

Jamming it into conversations with strong moral judgement attached to the opinion will make people dislike you, and it will not influence people who disagree with you. It will make them harden in their existing views because the emotional awfulness of what you are saying (implicitly accusing them of being bad people, or making them feel under threat) reinforces how correct they have been to have held those views.
